Synthesis of some new drugs supported on natural polymers

Abstract

AbstractIn this work the Synthesis of new polymers (chitin-binder -drug) as polymeric systems containing drug wascarried. The release of the drugs in vitro in deferent baffer solutions was studied. First part of the work includedthe extraction and purificion of chitin from Shrips Shells(1). The second part include the Synthesis of (chitinbinder-drug)(2). The third part was the release of pure drug from the polymer system at three pH different(pH1.2), (pH7.4), (pH9.4)(3)
